EDEN PRAIRIE, Minn. (AP) — Adrian Peterson is about to start his final NFL season in his 20s.

He will turn 30 next March, the age at which most running backs start to experience a steep decline in production. The Minnesota Vikings star says getting older “doesn’t apply to me.”

Peterson spoke on Thursday, the final day of the Vikings’ three-day minicamp. He says he is happy with the changes he’s seen under new coach Mike Zimmer and is eager to get going in a revamped offense led by coordinator Norv Turner.

He says his ability to come back from a torn ACL to rush for 2,000 yards proves that he shouldn’t be held to the same standards as other running backs.
